Diverticula are small, bulging pouches commonly found in the esophagus and large intestine. If we were to pass an endoscope in either of these areas of the GI tract, we would see what appears to be holes. Under closer examination, we can see that these holes lead into pouches. If organic material gets trapped within the diverticula it can cause irritation and even an infection. Although it is extremely rare to see the formation of diverticulum in the esophagus, they can be found within the colon in of all Americans over 50 years of age.
